Two sources of information appear to present slightly different figures regarding the number of job openings advertised in philosophy through the American Philosophical Association (APA) and PhilJobs—that is, through PhilJobs: Jobs for Philosophers—in recent years. (See update)

This is still down from a high in 2007 of nearly 1300, and a figure of around 900 in 2004:
